The Super Mario Galaxy 2: Original Soundtrack is a video game soundtrack for the game Super Mario Galaxy 2, and was released on July 10, 2010. Like the Super Mario Galaxy: Original Soundtrack, it is exclusive to Club Nintendo members in Japan. Unlike the original, however, only a 2-disc version is available and it holds all seventy songs from the game. Fifty of the songs are original compositions by Mahito Yokota, nine by Ryo Nagamatsu, and five by Koji Kondo. The rest are arrangements of compositions from earlier games, most of them by Mahito Yokota and one by Shigetoshi Gohara.[1] The game's music is performed by the Mario Galaxy Orchestra. The soundtrack has not been released outside Japan, as of yet. It has a combined playing time of 2:11:39.
